( 2^18 &times; 18^7 &times; 3^3 + 3^15 &times; 2^15 )/( 2^10 &times; 6^15 + 3^14 &times; 15 &times; 4^13 )   = ( 2^18 &times; ( 2 &times; 3^2 )^7 &times; 3^3 + 3^15 &times; 2^15 )/( 2^10 &times; ( 2 &times; 3 )^15 + 3^14 &times; 3 &times; 5 &times; ( 2^2 )^13 )   = ( 2^18 &times;2^7 &times; 3^14 &times; 3^3 + 3^15 &times; 2^15 )/( 2^10 &times; 2^15 &times; 3^15 + 3^14 &times; 3 &times; 5 &times; 2^26 )   = ( 2^25 &times; 3^17 + 3^15 &times; 2^15 )/( 2^25 &times; 3^15 + 3^15 &times; 5 &times; 2^26 )   = ( 2^10 &times; 2^15 &times; 3^15 &times; 3^2 + 3^15 &times; 2^15 &times; 1 )/( 1 &times; 2^25 &times; 3^15 + 3^15 &times; 5 &times; 2^25 &times; 2 )   = ( 2^15 &times; 3^14 &times; ( 2^10 &times; 3^2 + 1 ) )/( 2^25 &times; 3^15 &times; ( 1 + 5 + 2 ) )   = ( 1 &times; 1 &times; ( 9216 + 1 ))/( 2^10 &times; 3 &times; 8 )   = 9217/( 1023 &times; 3 &times; 8 )   = 9217/24552   @Tina
